The basic idea behind WPS is that having physical access to the AP to hit a button and reading a sticker would provide a more secure implementation of Wi-Fi authentication. Everything was well and good in the WPS world, until last winter, when a security researcher discovered the Achilles Heel in the implementation. From these 7 digits, we can see that there are 10,, possibilities since each of the 7 digits can be , with repeats allowed.
When a PIN is being examined by the AP, the first 4 digits 10, possibilities are checked separately from the last 3 digits 1, possibilities. This translates into a malicious user only needing to make at most 11, guesses, which a computer can handle in a matter of hours! Using this security combination provides the most secure Wi-Fi network possible today, and gives you the peace of mind you need to "set it and forget it.
That would undo any other security steps you may be taking. Contact the manufacturer directly. Keep your router up to date. To make sure you hear about the latest version, register your router with the manufacturer, and sign up to get updates. Some routers have features that can be convenient but weaken your network security.
WPS lets you push a button on the router to connect a device to the internet instead of entering the network password. Lastly, UPnP lets your devices find each other on the network.
These features may make it easier to, say, add devices to your network or let guests use your Wi-Fi — but they can make your network less secure. Set up a guest network. Many routers let you set up a guest network with a different name and password. At the beginning, however, not much emphasis was placed on security: unencrypted transmission and no user authentication requirements meant that anyone within the appropriate area had access to a wireless network.
Ultimately, the requirement of WLAN security promoted the development of the following encryption and authentication methods:. Whether this is unintentional or for compatibility reasons to grant access to older devices is incidental.
What is clear is that networks like this are at a high risk of unauthorized access — one of the main reasons for the critical assessment of WLAN security. Additional errors that make it easier for attackers to intercept data include:.
In addition, wireless networks are vulnerable to common DoS or DDoS attacks as well as so-called evil twin attacks. With the latter, malicious attackers plant fake wireless access points in the network with special firmware. Network users believe these to be real and then connect to them.
The evil twin responds with its own authentication request and receives the WLAN access data from the unsuspecting network device. It also takes over the MAC address of the client MAC spoofing , gaining all necessary data to establish the connection. Publicly accessible WLAN points are particularly at risk from this kind of attack. The weaknesses listed above show the importance of becoming familiar with various possibilities of WLAN security. If you expect to get the best protection with a firewall and a secret password, you will quickly be convinced otherwise in the event of a targeted attack.
The more careful you are with the configuration and management, the more secure your network will be later on. Specifically, the settings you make for this hardware component determine whether an attacker can gain access to your wireless network within a few seconds, or whether it remains just an attempt. These are the most important configuration steps:.
Access to this interface is achieved through an administrator account with a default username and password. Change this administrator account log-in information at the beginning of the configuration.
You can write it down and store it in a safe place, but do not store it on your computer without proper password storage. Instead, use network devices that support WPA2 and do not rely on old encryption methods. If you are using WPS configuration software, you should only switch it on when it is needed.
So far, only password attacks have been known for WPA2; in particular brute force attacks and dictionary attacks are very popular with cyber criminals. The importance of a complex WLAN password therefore cannot be underestimated. Eytan is a graduate of University of Washington where he studied digital marketing.
